Work Text:
Soap only had one rut a year, thank god. Ghost didn’t think he’d survive if the border collie hybrid went into rut more often than that. Even more luckily, it rarely lasted longer than twenty-four hours. Still, when they applied for medical leave, they always requested a week off to prepare and recover.
If Soap was bad at reigning in his herding instincts normally, he was almost insufferable the closer it got to his rut. Ghost couldn’t even go to the bathroom without Soap pushing him this way and that. As a cow hybrid, Ghost rarely minded, but even his patience had its limit. The second it became too frustrating to leave his suite—being an officer had some perks—the pair officially entered rut season.
Soap fetched (pun intended) a few more water bottles, some fresh food to stock Ghost’s mini-fridge with, a change in bedding, and some spare clothes, and their door was officially locked. Both of them hydrated as much as they could but avoided solid foods the closer they got to Soap’s rut. The first time they’d done this, they’d made the mistake of eating a full meal the night before, and both of them ended up with stomach cramps halfway through the rut; not to mention how awkward it was to take a shit with a hard cock or leaking cunt. By the second year, they’d perfected their planning and methods.
Ghost rested while Soap scented the room extensively, marking his territory and growling if someone walked by the room. When he wasn’t doing that, though, the two cuddled and talked about everything and nothing: their plans for the future, what they wanted to eat the next day, their thoughts on the newest recruits…. Sometimes, their talks turned to retirement and children. Ghost still took testosterone, but he wasn’t on any other birth control, and they didn’t use condoms during Soap’s ruts (both of their animal brains hated it too much). Pregnancy wasn’t impossible, and Ghost had admitted to being open to carrying a calf or pup (depending on whose genetics won), but it wasn’t something they actively planned for, despite their shared breeding kinks. They agreed, though, that if Ghost ever did end up pregnant, it would be his choice to carry or terminate the child.
***
Soap woke up early on the day of his rut with an almost painful erection and lust clouding his thoughts. He quickly woke Ghost up—Simon, they could be Simon and Johnny now—and barely restrained himself from shoving his face into Simon’s already-weeping cunt. He had pleasantly surprised Simon the first time they’d spent Johnny’s rut together, how Johnny first ate him out before actually fucking him. As it turned out, cunt was one of Johnny’s favourite foods, and he ate it like a man starved. His tongue was longer than average, and he eagerly used that added length to lick and slurp an orgasm out of Simon in seconds. His lips latched around Simon’s dick next as he tried to suck Simon’s very soul out of it. By the time Simon came a second, or even third, time, he was panting and relaxed enough to take Johnny’s cock easily.
“Johnny,” Simon whined, pulling his mate into a desperate kiss. He could taste himself on Johnny’s tongue.
The dog hybrid’s tail wagged so fast it was in danger of spraining (which had happened several times before). “Fuck, you taste so good, Si,” he groaned. “Love your cunt so much. Gonna fuck you and eat my cum out of it.”
Simon’s face down to his pecs heated up. “Thought you wanted it to take,” he teased. It wasn’t their fault they shared a breeding kink; it was their animal hindbrains’ faults.
Johnny growled and finally reached down to help get his cock in Simon’s hole. No matter how often they fucked, Johnny’s sheer size punched the breath out of Simon’s lungs. He immediately set a brutal pace, Simon’s tits bouncing almost painfully with the force. They met in a kiss that was more teeth than lips, and then Johnny gripped one of Simon’s horns and pulled his head to the side. He eagerly licked and bit at Simon’s neck, paying special attention to the more sensitive patches of skin.
Simon could only lay there and take it, panting and gasping with each thrust. He refused to let out any louder sounds; Johnny had to earn those. He couldn’t hold back a soft whimper, though, when Johnny began to play with his nipples. They’d always been sensitive, and out of his rut, Johnny enjoyed making Simon cum just by playing with his tits.
Soon, Johnny’s knot caught on Simon’s rim, and he only had to push it in before he was cumming deep in Simon’s cunt. The first knot always popped the quickest, and Simon shuddered through an orgasm of his own as he felt hot seed coat his insides. When Johnny kissed him again, it was gentler and sweet.
As soon as his knot went down, Johnny pulled out and flipped Simon onto his front. He chuckled and spanked Simon’s ass as the cow hybrid eagerly got onto his hands and knees, arching up so prettily. Simon had to choke back a moan from the contact but couldn’t stop himself from sticking his ass higher, feeling slick practically gush down his thighs.
“What a pretty cum slut you are,” Johnny cooed. “One load not enough for you, sweetheart?”
Simon’s face burned. “You’re just as desperate as me,” he muttered.
He could hear Johnny’s unrepentant grin. “Aye, I am.” Then he sheathed himself in Simon’s wet heat in one thrust and started fucking him relentlessly once more.
From this angle, he reached even deeper inside Simon, just barely missing his cervix. Simon had to fight back each whine and moan that wanted to escape his lips. Then Johnny draped himself fully across Simon’s back and used his tits to fuck him back on his cock.
“Fuck!” Simon cried, his tail thrashing with overstimulation.
Johnny just bit his shoulders and continued to pinch and pull Simon’s nipples in time with his thrusts. The dog hybrid would easily admit to having a thing for Simon’s tits and would play with them constantly, tricking them into thinking a calf was trying to nurse. Simon’s chest didn’t swell with milk, but enough would build up that when Johnny was particularly rough with them, drops of cream would drip from his nipples.
Outside of his rut, Johnny had a habit of edging Simon. During, though? Simon couldn’t keep track of how many orgasms he had. This might’ve been his fifth or his sixth in barely fifteen minutes, and he was so sensitive in his cunt—still being pounded mercilessly; his dick—where Johnny’s balls kept slapping against it; and his chest—still being roughly kneaded and groped. Johnny’s small claws kept lightly scratching the flesh around Simon’s pecs, too, only adding to the overwhelming sensations.
It wasn’t long before they both came again, this time the tip of Johnny’s dick bullying its way past Simon’s cervix as his knot popped in. Simon couldn’t stop the small bellow that escaped his throat or the way his legs tried to kick back from how intense everything was.
The two stayed like that for a moment, just catching their breaths. Johnny’s knot was still swollen as he fumbled for the water bottles they’d left on the bedside tables. They drank awkwardly but eagerly, though Simon felt some humiliation from needing to be watered while on his hands and knees. They only drank half a bottle each, and by then, Johnny’s knot had gone down enough to pull out again. Simon had to choke back a sound of distress at the feeling of some of Johnny’s cum leaking out of his hole. His horny cow hindbrain hated being empty (his horny human brain did, too, but he would die before admitting that).
“Aw, your pretty hole tightened up suddenly,” Johnny rumbled. “Din’ worry, sweetheart; I’ll plug you up when we’re done, so nothing escapes your needy little cunt.” He still nosed at it, though, licking the drops of spend that had escaped and making Simon choke on a whine.
“Fucking- ah- arsehole,” Simon panted, thighs trembling. He opened his mouth to say more, but Johnny flipped him over again and bent his knees up to his long ears.
Johnny grinned wolfishly down at him (pun intended). “None of that now,” he crooned. “Only good boys get their needy cunts fucked. Din’ you wanna be my good boy?”
Simon’s face burned as another gush of slick pushed more cum out of his hole. He stubbornly refused to answer that.
“Din’ worry, dear,” Johnny just said. “I’ll make you say it, eventually.” It was equal parts a promise and a threat, and Simon forced another whimper down at it.
He could barely hold back his sounds, though, as Johnny sheathed himself once more in his cunt. The dog hybrid’s cock went in easier each time, and Simon shuddered as he imagined how sloppy and wet his hole would be by the end of the day.
While Johnny was quieter during the first two rounds, just getting the worst of his rut out of his system, this time, he picked up the dirty talk. “You feel like a dream no matter how many times I fuck you,” he groaned. “Always so tight. So desperate to milk my cock. Such a good little cum slut for me.”
Simon’s self-control waned, soft gasps escaping him with each thrust.
“I bet the whole fucking base could cum in you and you still would na’ be satisfied,” Johnny continued. “Could tie you up and let anyone use your greedy cunt and you’d still beg for more.”
The cow hybrid failed to stifle a broken moan.
Johnny grinned. “You like that idea? Being nothing more than a cum dump for the whole base?” He groped Simon’s tits. “Make you a proper dairy cow. Knock you up over and over ‘til your tits are just bursting.”
Simon keened as milk spurted from his abused nipples. He could barely hold back his whimpers as Johnny lapped up the milk. The taste only made Johnny more feral, and Simon could only scrabble at his back in a desperate attempt to anchor himself, physically and mentally. He’d cum so many times already that he could feel his human mind retreating and the animal one taking over. He refused to give in that easily, though.
“Not- fuck- your fucking dairy cow,” he moaned.
Johnny groaned into his chest. “Then why'd your cunt squeeze me so eagerly when I said it?”
Simon's cunt squeezed him again. “Shit- Fuck you-! Ngh!” The sound he let out as Johnny knotted him a third time that morning was embarrassingly needy.
“Din’ worry, sweetheart,” Johnny cooed. “I know what you need, and I’ll give it to you. Stuff you so full you’ll feel it for days. Keep fucking you ‘til there’s a calf in there; give you as many calves as you want.”
Simon panted openly, now, lacking the strength to keep his mouth shut or his tongue inside his mouth. Johnny spit in Simon’s open mouth, and Simon couldn't hold back a keen.
“What a good slut,” Johnny purred. “Weren’t you saying something about na’ being a stupid, horny dairy cow?”
“Fuck you-oo.” To Simon’s mortification, his words trailed off into a moo.
Johnny’s smile was victoriously predatory. “There’s my pretty dumb cow. Just here to be my cocksleeve. Dinnae worry your pretty little head about anything, sweetheart, and just let me take care of you.”
The next few hours passed in a blur for Simon. He vaguely remembered being on his hands and knees again, and he was pretty sure one time Johnny fucked him against the wall. He definitely rode Johnny’s cock at least once, too, his cowbell jingling as he bounced desperately on Johnny’s dick. They paused at least one more time to hydrate, too, and though he couldn't remember it well, Simon suspected he ended up drinking from a bowl instead of a bottle. The shame of it made his insides spasm.
He lost track of how many times Johnny knotted him, but it had to have been at least seven times, maybe even eight. Simon could no longer speak, only moaning and mooing, feeling more and more like the stupid dairy cow Johnny kept saying he was. It was all part of the play, but Simon’s horny, animal hindbrain had latched onto it desperately.
It got to the point where Simon would moo in protest when Johnny pulled out to switch positions again, and if he ended up on his front, Simon found himself reaching back to pull his hole open enticingly. It was so hard to think about anything except being fucked and bred.
Johnny manoeuvred Simon onto his back again, and Simon used his shaking arms to pull his knees up with a needy whine.
The dog hybrid had turned more animalistic for a while, too, communicating more in barks and growls than speech, but as his rut finally began to taper off his human mind came back to him. He cooed as he petted Simon’s quivering pussy.
The cow hybrid keened and pulled his legs back more with a pathetically desperate face.
“Aw, you hate being empty, huh?” Johnny cooed.
Simon mooed and wiggled his hips enticingly. Johnny spat on his cunt and Simon let out a needy cry.
Johnny chuckled, only a little mean. “Don't worry sweetheart. I'll plug you up so nicely after we're done.” He sunk back into his mate’s loose cunt and immediately set a brutal pace.
Simon eagerly met every thrust, crying out in ecstasy with each one. His face was messy with drool and tears, and milk had dried stickily all over his chest. Bites and scratch marks littered his entire body from his neck to his thighs, and his cunt was unbelievably red and swollen from hours of abuse.
Johnny reached down to play with Simon’s dick as he continued to pound him, and Simon let out a bellow and squirted almost violently. The spasms from his cunt brought Johnny over the edge once more, and he swore Simon’s stomach had swollen a bit from all the cum stuffing him.
Simon didn’t stay still, though, grinding desperately against Johnny’s knot.
“Fuck, you want one more, sweetheart?” Johnny gasped.
Simon just mooed wantonly.
Johnny’s knot softened enough to pull out, making Simon whine in distress. “Shh, I ken, baby. I’ll put it back in, but you gotta turn around for me first.”
What little remained in Simon’s brain registered the request, and he scrambled to present himself.
Johnny cooed and massaged Simon’s ass cheeks. “Just like a proper bitch in heat. My horny little heifer.”
Simon pushed his ass higher and shook his hips, pleading with big, watery eyes.
Johnny took pity on him and slammed home, definitely breaching Simon’s womb. The cow hybrid keened and pushed back just as roughly. Johnny grabbed him by the tits again, pulling at his nipples until milk spurted out. Simon cried out and pushed his chest into Johnny’s hands, his tongue lolling out of his mouth and getting drool all over their sheets.
This last round seemed to last an eternity, Johnny losing himself in Simon’s slick heat as Simon became drunk on cum.
All good things must end eventually, though, and Johnny’s knot popped in one last time. Their visions whited out from the force of it, Simon squirting from both his crotch and chest. Johnny nearly collapsed on top of Simon, but Simon fully fell onto the bed. Both of them trembled with the aftershocks. It took another several minutes for Johnny’s knot to fully deflate and for his dick to go soft for the first time all day.
He began to pull out, but Simon weakly pressed back against him with a distressed sound.
“Oh, poor dear,” Johnny panted. “I ken, but we need to get cleaned up, sweetheart. You’ll be more upset if you stay all dirty.”
The cow hybrid continued to protest, so Johnny sighed and searched for one of Simon’s dildos he denied having in his nightstand. It was difficult while still anchored in Simon, but he found one that would work.
He pushed it in before Simon could complain about being empty then got off the bed to stretch. Every muscle felt sore but in a good way. His skin was sticky, though, and the fur on his ears and tail was greasy. He cleaned himself quickly before coming back to Simon with a warm washcloth and wiping his mate down.
When Simon got turned onto his back, he smiled dopily up at Johnny and spread his legs with an inquisitive moo.
Johnny chuckled and petted the cow hybrid’s pudging belly. “Let’s rest first,” he said, “then we can see about going another round.”
He led Simon to the bathroom, supporting most of his weight as Simon’s legs shook, especially when he would clench on the dildo to keep it in, making it brush his G-spot. Johnny sat him on the toilet and then changed the bed sheets.
After they were both sufficiently clean, he brought Simon back to the bed to cuddle and rest. Johnny got out a pre-prepared platter of diced fruit, nuts, and dried pork rinds (the latter exclusively for himself) and gently coaxed Simon into eating and drinking more water.
***
Simon slowly came back to himself, feeling satisfied all the way down to his bones. He registered the taste of something sweet on his tongue, and as he gained more consciousness he realised Johnny was feeding him diced fruit.
The dog hybrid himself was pressed against Simon’s back, spooning him. Simon still felt stuffed, but as he clenched his cunt he realised it was a knotted dildo, not Johnny’s cock. Part of him felt disappointed, but it still filled him nicely and kept Johnny’s cum deep inside. Otherwise, though, he was clean and warm.
Simon sighed contentedly as Johnny continued to gently feed him fruit while petting his flank.
“Back with me, sweetheart?” Johnny asked softly, pressing a kiss to Simon’s temple.
Simon signed and leaned back against his mate. “Yeah,” he said, voice hoarse but not painful. “What time is it?”
He felt Johnny check his phone. “My rut ended about an hour ago. It’s midnight now, actually.”
“No wonder I feel so sore. How many rounds did you even go?”
Johnny’s voice was proud. “We finally hit ten knots!”
Simon’s hand went to his slightly distended stomach. “Sure feels like it.” He absentmindedly pressed down to feel the cum in his guts and let out a small whimper.
Johnny chuckled. “You were so upset when I pulled out after my last knot finally went down.” He pressed gently on Simon’s stomach, too. “Want me to take the dildo out now?”
“Don’t you fucking dare.” He smacked Johnny’s band and tightened around the hand to make sure it didn’t come out. A keen escaped his lips as Johnny instead pressed the dildo further in, and his tail lashed in annoyance. “Twat,” he muttered.
Johnny just giggled and cuddled closer.
***
Everything usually returned to normal soon after Johnny’s rut and their medical leave ended. They officially went back to their own quarters while sneaking into each others beds for a fuck or a cuddle and Price pretended to not notice; they began training new recruits again and joining exercises with the rest of the task force; Soap tried and failed to avoid herding everyone causing Gaz to make fun of him.
However, around two weeks later, both dog hybrids began acting strange around Ghost. Gaz started following Ghost with a confused expression, constantly scenting the air around him. Meanwhile, Soap got worse at herding Ghost and even began herding others away from him, snapping if they got too close.
Ghost himself felt off, feeling nauseous when he woke up or if he smelled the barest hint of spice in the air. His chest began feeling sore, too, and his nipples more sensitive.
Price and Ghost figured it out at the same time, and the Captain called Ghost and Soap to his office with an exasperated look.
The ox hybrid rubbed his forehead tiredly. “I thought you bastards used some form of protection,” he said. “Either you lied to me, or it failed. So what are you two planning to do about this?”
Ghost was grateful for his mask hiding his bright red face.
Soap, though, just cocked his head in confusion. “Do about what, sir?”
Fuck, Ghost’s face was on fire.
Price had never looked older or more exhausted. “Do you want to tell him, Simon?”
Soap turned his perplexed face to Ghost.
The cow hybrid swallowed. “I think I’m pregnant.”
“No, you’re definitely pregnant, Ghost,” Price corrected. “Everyone can smell it on you.”
Soap’s eyes widened. “Wait- Seriously? Are you? You are?” His tail started wagging so violently that Ghost feared he’d hurt himself. “We’re having a baby?! Wait- Do you wanna keep it?” He turned completely serious. “I dinnae wanna pressure you either way; it’s your decision, Simon.”
He was so earnest that Ghost’s heart ached with affection. They’d already talked about the possibility of children so many times, and Ghost trusted Soap so much it scared him. He knew Soap wanted kids, and he could tell the dog hybrid would be a wonderful father if they ever chose to go that route. However, he also knew Soap would fully support him if Ghost chose to abort the fetus, too. After all, they were still happy in their careers and hadn’t even gotten married yet. It was Ghost’s choice, and Soap would be there every step of the way no matter what.
Simon made up his mind.
***
“You fucking arsehole!” Simon screamed as another contraction hit. “I’m never letting you cum inside me again! Shit, tell me it’s almost out!”
”You’re doing so good,” the doctor soothed. “She’s crowning now! Give me one more big push!”
Johnny winced under Simon’s bone-crushing grip on his hand but kept petting his hair and reassuring him. “You’re doing amazing, sweetheart! It’s almost done! You’re almost there!”
Simon let out another pained cry, and the sound was joined by a high-pitched whining. The doctor quickly cut the umbilical cord and wrapped the newborn in a towel.
“It’s a girl!” she exclaimed happily.
Simon panted hard but smiled softly as his beautiful little calf was placed in his arms. “She’s so small,” he whispered.
”She’s perfect,” Johnny said, tears in his eyes and a wide grin on his face.
The calf had dark, fluffy ears and a soft tuft at the end of her tail. Her skin was closer to Johnny’s tan, but her eyes revealed a brown dark enough to rival Simon’s. Johnny was right; she was perfect.
”Hello, Heather.”
